• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"ґрунтова (основеіе\\" OR ((основеі\\" OR основііеі\\") OR основні\\"))) OR (\\"ґрунтова основ\\"))~\"".
• Removing quotes may allow a broader search: (( ґрунтова (основеіе OR ((основеі OR основііеі ) OR основні ))) OR ( ґрунтова основ ))~.
